The present invention relates to a system and method for pitch control of rotor blades. A wind turbine includes a hub rotatable about an axis and blades coupled to the hub. The blade includes an innerblade portion having a first end and a second end. The inner blade portion is coupled to the hub at a first end and extends radially outward from the hub to a second end. The blade also includes an outer blade portion having a first end and a second end. The first end of the outer blade portion is pivotally coupled to the second end of the inner blade portion. 用于转子叶片的变桨的系统和方法。一种风力涡轮包括能够围绕轴线旋转的毂和联接到毂的叶片。叶片包括具有第一端和第二端的内叶片部分。内叶片部分在第一端处联接到毂，并且从毂径向地向外延伸到第二端。叶片还包括具有第一端和第二端的外叶片部分。外叶片部分的第一端可枢转地联接到内叶片部分的第二端。
